MODIFIED - 1/8" Mono Plug for a 'portable' Radio's Ground Connection :
1. Remove the Tip Section of the 1/8" Mono Plug leaving
just the Rear Barrel Section and Solder Terminal.
2. Solder a Wire (Ground Wire) to the Solder Terminal.
3. Connect the Wire to Ground or the Shack's Ground.
4. Plug the 1/8" Mono Plug into the Radio's Earphone Jack.
Your Radio is now Grounded.


I might be missing something here, but ....

If I plug the modufied plug into the earphone jack, the radio's speaker
would still be taken out of the circuit. Now that the earphone jack is no
longer usable, and the speaker is no longer inline, there would be no audio.
In a strange way it makes sense, no audio, much less noise.
